  A solution ofwas kept in an iron pot. After few days the iron pot was found to have a number of holes in it. Explain the reason in terms of reactivity. Write the equation of the reaction involved.               

Answer:

                  As iron is more reactive metal than copper, it displaces copper from copper sulphate solution. The following reaction takes place                                 Since, iron takes part in this reaction, therefore holes are produced at places where iron metal has reacted to form iron (II) sulphate.
